Abstract :

As FDM Technology Gains Wider Acceptance, There Has Been An Increasing Interest In Polymers With Improved Mechanical Properties. Despite Its Popularity Due To Biodegradability, Easy Processability, And Environmental Friendliness, PLA Usually Displays Poor Performance In Terms Of Stiffness And Toughness Necessary For Engineering Applications. To Improve The Material Behavior, Hybrid PLA Composites Reinforced With SiC And Al2O3 Nanoparticles Were Fabricated And Experimentally Analyzed. Three Different Hybrid Filler Compositions Were Used, While Keeping The Total Amount At 3 Wt.%, Including: 2.25 Wt.% SiC + 0.75 Wt.% Al₂O₃, 1.5 Wt.% SiC + 1.5 Wt.% Al₂O₃, And 0.75 Wt.% SiC + 2.25 Wt.% Al₂O₃. Composite Filaments Were Made By Extruding And Further Used For Manufacturing Test Specimens. Tensile, Flexural, Compression, And Impact Tests Were Conducted To Characterize The Samples Behavior. According To The Experimental Results, The Use Of Ceramic Fillers Led To An Improvement In The Mechanical Properties Of PLA. From All Compositions, The Highest Tensile Strength (53.46 MPa) And Compressive Performance Were Shown By The Sample With An Equal Proportion Of SiC And Al₂O₃ Fillers (1.5 Wt. %). In Turn, The Flexural And Impact Resistance Showed Maximums For The Sample With The Majority Of Al₂O₃ (0.75 Wt. % SiC + 2.25 Wt. % Al₂O₃), With 94.90 MPa Flexural Strength Recorded. Thus, The Positive Effect On Mechanical Properties May Be Explained By The Synergistic Effect Of The Filler Composition Used In The Analysis.
